  1. high levels of unemployment,
  2. low wage rates,
  3. lack of promotion opportunities,
  4. poor social infrastructure,
  5. political instability,
  6. religious persecution,
  7. desire to seek new experiences

18
Q

how can we calculate the dependency ratio?

A

formula:

number of people aged under 15 and over 65 decided by the number of people aged between 15 and 65

19
Q

how can the dependency ratio change?

A

if a population increases due to immigration, more people might join the labour force and the ration would decrease. hence increases in the tax revenue of the state

if a population increases due to a higher birth ration the ratio goes up and there might be a higher demand on government funds.

20
Q

what are economic consequences of an increase in emigration?

A
  1. a rising dependency ratio
  2. opportunity costs
  3. ‘brain drain’
  4. smaller domestic market
  5. upward pressure on Irish wage levels
  6. demand for state services
  7. unemployment reduced
  8. international connections
  9. reduction in social costs
  10. loss of potential investment
21
Q

what is ‘brain drain’ ?

A

graduates who have acquired skills needed to help us move toward economic growth may emigrate in search for employment or better job opportunities.
it robs the economy of the skills and qualifications invested in them, which are an important aspect of economic recovery and strength .

22
Q

what are economic consequences for a country experiencing increased immigration?

A
  1. increased demand for goods/services
  2. improved dependency ratio,
  3. government revenue increases,
  4. reduction in labour shortages
  5. greater utilization of services
  6. new skills/traditions within society
  7. pressure on provision of state services
  8. pressure on infrastructure
  9. drain of state finances
  10. exploitation of immigration
  11. increased dependency ratio
  12. resentment/ racism
  13. land and property values increase
23
Q

a population who…

  1. lives longer
  2. has an increasing average lifespan
  3. has a growing percentage who are in a n older age bracked
24
Q

what are possible economic effects of an aging population on the Irish economy?

A
  1. pressure on the provision of state pensions
  2. increased tax burden
  3. increased government expenditure
  4. changing pattern of demand
  5. participation rate falls
  6. reduced mobility of labour
25
Q

what is the census ?

A

the census is the official count of the nation’s people and a compilation of economic, social and other data. it is used by the government in formulating development policies and plans. it usually occurs every five years.

26
Q

what are the economic uses of a census of population in Ireland?

A
  1. shows demographic changes,
  2. infrastructural requirements,
  3. regional policy,
  4. pension planning
27
Q

why is the census of population important ?

A

it gives an overall picture of the social and living conditions,
helps in planning of infrastructure, education systems and health care,
to get an accurate indication of net migration

28
Q

how does world famine affect the global perspective of our rising population?

A

95% of human population growth is occurring in countries already struggling. a high percentage of income is spent on basics like food, housing and clothing. little finance is left to invest in the economy.

this perpetuates the poverty cycle.

29
Q

is there a fall of population in developed countries?

A

it is unlikely to change in the next 40 years and should remain at around 1.2 billion.
fertility is below the replacement level in many developed countries.
it would probably decline without inward migration.

30
Q

global perspective : how does our rising population affect the enviremant?

A

overpopulation means less available land for agriculture, hence increased demand for chemical agriculture band genetically modified crops. (increase in food production)

fresh water supplies are decreasing. the amount of available water per person will drop by 74% between 1950 and 2050. (South Africa, California )

31
Q

what was Thomas maltus’ theory of the growing population?

A

population will increase in a geometric progression (1,2,4,8,16,…) while the resources to feed the population will grow by arithmetic progression (1,2,3,4,…), which Leeds to food shortages…

book: An Essay of the Principle of Population

32
Q

can we see maltus’ theory of population growth being proven or not?

A

yes - in some less developed countries

no- in developed countries,
due to improvements in agricultural technology & a slow down in population growth
